Spare paper roll

ABSTRACT

An active code carrier is located inside a spare paper roll that includes a tube or core. The code carrier interacts with either a reading head, or a writing head. This enables roll-specific data to be read or updated at any time. This is particularly useful for automated roll transport and roll handling systems.

FIELD OF THE INVENTION

The invention relates to a spare paper roll such as a paper web roll.The roll is wound on a winding core or tube. A core carrier, that has adata memory is provided in the spare web roll or in the tube.

DESCRIPTION OF THE PRIOR ART

It is generally known to provide spare paper web rolls with a 16-digitbar code identification on their outer packaging, for example inaccordance with a recommendation of the IFRA Newsprint Committee, forexample. This numerical code includes, for example, number of the theroll, the weight of the roll, the type of packaging, the basis weight,the quality, as well as the manufacturer's code. As a rule, this barcode identification is scanned by means of a laser scanner.

In connection with this coding, the lack of legibility because of damageto the code support is disadvantageous, for example. This can result inthe loss of information or to incorrect information.

SUMMARY OF THE INVENTION

WO 98/28213 shows a spare web roll with a tube. An active code carrieris arranged in the tube.

DE 39 12 488 A1 describes a method for transmitting product informationregarding a textile bobbin by providing either the winding core or thetube for the spare web roll, or the spare web roll itself with a corecarrier which can be activated and which has a data memory. memory chipwhich can be read and erased.

The object of the invention is based on providing a spare web roll withan information carrier.

The advantages which can be achieved by means of the present inventionreside, in particular, in that the code carrier is arrangedindependently of the outer packaging, or respectively the outer layer ofthe web, so that the code carrier can be interrogated at any time. It isfurthermore possible to provide the code carrier with new, orrespectively supplemental data, and to store these. Such data could be,for example, information regarding a new destination, length of theremaining paper, particulars of the quality—for example, a “beating”roll—and the like.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

A spare web roll, for example a spare paper web roll 1 for a web-fedrotary printing press, has a continuous tube 3 in the area of its axisof rotation 2, on whose tube body a web 4 of material has been wound,all as seen in FIGS. 1 and 2. A star-shaped, for example three-armedholder 7 is arranged in the end area of the tube, and in particular inthe area of the interior diameter, or respectively interior 6 of thetube 3, whose arms 8, 9, 10 rest resiliently against the interiorcircumference 6. For example, the holder 7 supports a cylinder-shaped ordisk-shaped code carrier 12, which can be activated, i.e. can be codedand decoded, coaxially with the axis of rotation 2. The code carrier 12is an electronic component, which can be coded by inductive means.

The holder 7 can be inserted, for example into the end area of the tube3 of a spare paper web 1 roll, i.e. into the interior 6 of the tube 3,in such a way that it remains in a temporary first position B, i.e.close to the lateral edges 13 of the web of material 4 as—represented indashed lines in FIG 1. Only when the spare paper web 1 roll is placed onthe shaft, is the holder 7 pushed into a second position C by means of aclamping cone, not represented. The holder 7 will now be in the positionshown in solid lines in FIG. 1.

After the roll is used up, for example, the holder 7 can again be takenout of the tube 3 by removing it. For this purpose the arms 8, 9, 10 canhave bores 14, 16, 17, for example, behind which a suitable tool canreach.

A number of code carriers 18, 21, 23, 26 are represented in respectivelydifferent fastening positions in FIG. 3. However, only one of which isused.

A code carrier 18 is arranged in the front face 19 of the tube 3, i.e.in the tube body, and may for example be pressed into a bore.

A code carrier 21 is fastened to the inner surface 22 of the tube 3,i.e. in the interior 6 of the tube 3, for example by gluing.

A code carrier 23 is arranged in the tube body 3. In this case, the tubewall 24 can have a bore into which the code carrier 23 is pressed.

It is also possible to arrange a code carrier 26 in the webs of material4 which are close to the tube 3, i.e. the inner or lower ones, i.e. tointroduce it from the direction of the lateral edges 13 of the webs ofmaterial 4 into an area close to the edge, for example to press it in.Therefore the code carrier 26 is outside of and in the vicinity of thetube 3.

The code carriers 12, 18, 21, 23, 26 arranged in the interior of thetube 3 or in the vicinity of the tube 3, for example the code carrier 18located in the front face 19 of the tube 3, are connected with one ofthe recording and reading heads 27, 28, 29. Such recording and readingheads 27, 28, 29 are, as shown in FIG. 4, stationed along a conveyancepath for movable spare paper web transport carriages, for example therecording and reading head 27 in the vicinity of a storage facility forspare paper web rolls 1, the recording and reading head 28 is locked inthe vicinity of a preparation station for spare paper web, and therecording and reading head 29 is located in the vicinity of a rollchanger.

Each recording and reading head 27 to 29 consists of an electroniccomponent, which transmits energy 37 and information 38 in a contactlessmanner to the code carrier 18. On the other end, all recording andreading heads 27 to 29 are connected with each other via a data bus 39,as well as with an evaluation unit 41 and a control device 42, as wellas a master computer 43, all as shown in FIG 4. The master computer 43has an input station 46.

The code carrier 18, as well as the other code carriers 12, 21, 23, 26,are essentially embodied as data memory devices, and respectivelyconsist of an electronic component with a memory and logical controldevice. The above mentioned code carriers are, for example, designed asEEPROM versions, and can be written on and read out, for example, withup to eight Kilobytes.

If, for example, a spare paper web roll 1 is moved out of the storagefacility—the transport carriages are, for example, pulled by means ofunder-floor or driverless transport systems—the code carrier 18 locatedin the tube 3 of the spare paper web roll 1 passes by therecording/reading head 27. As soon as the code carrier 18 comes into theactive area of the recording/reading head 27, the energy 37 required fordata transmission is built up and the data 38 are transmitted by therecording/reading head 27 to the code carrier 18, and the data 44 aretransmitted by the code carrier 18 to the recording/reading head 27,each in a frequency range of, for example, 70 Kilohertz. Such data canbe, besides the data entered by the manufacturer: new destination, forexample the spare paper web preparation station, remaining length ofpaper, particularities of the paper, for example a “beating” roll.

The data, which are inductively coupled in by the code carrier 18, areconverted into a digital energy signal and conducted to the evaluationunit 41. The evaluation unit 41 manages the data transfer 37, 44 betweenthe recording/reading head 28 and the code carrier 18 and is used as anintermediate memory. The evaluation unit 41 is the connecting memberbetween the master computer 43, or respectively the control device 42,and the code carrier 18. Data can be erased or new data can be added,such as for example, a new destination, the gluing preparation stationand the type of the glue tip. Following the gluing preparation of thespare paper web roll 1, it is possible to enter a further destination,for example a roll changer, by means of the recording/reading head 28.After a portion of the spare paper web roll 1 has been used, anotherentry to the roll data takes place by means of the recording/readinghead 29, as well as a new destination, for example a storage facility.

It is also possible to arrange only stationary reading devices for thepurpose of reading out the destination at appropriate positions on thetransport path, for example at switches.

In accordance with a further preferred embodiment, the recording/readinghead 29 can be arranged in the roll changer, i.e. for example in a rollcone of a support arm of the roll changer, so that a data exchange cantake place between the recording/reading head 29 and a code carrier 18while the spare paper web roll 1 is still on the shaft. Alternatively itis also possible to fasten the recording/reading head 29 on the end ofthe support arm of the roll changer.

The data exchange preferably takes place during the run-out of the sparepaper web roll 1, i.e. while the spare paper web roll 1 turns slowly.

It is also possible to utilize a code carrier 12 arranged in the area ofthe imagined axis of rotation 2 of the spare paper web roll 1 in theinterior 6 of the tube 3. In this case the recording/reading head 12 isarranged in the direction of an extended axis of rotation 2 on theexterior of a support arm of the roll changer. Here, the clamping coneis designed to be hollow.

While preferred embodiments of a spare paper roll in accordance with thepresent invention have been set forth fully and completely hereinabove,it will be apparent to one of skill in the art that a number of changesin, for example, the material used to construct the tube, the type ofpress with which the spare paper roll will be used, and the like may bemade without departing from the true spirit and scope of the presentinvention which is accordingly to be limited only by the followingclaims.
